I still struggling when using R on Knime but I'm getting somewhere :)
My task is run some visualizations from corrplot package (https://cran.r-project.org/web/packages/corrplot/vignettes/corrplot-intro.html)
I've done the correlation matrix and its perfect :)
But I can't plot the visualizations :(
Should I use a new R snipet node only to plot
I'm doing this in just one R Snipet:
knime.out <- as.matrix(cor(knime.in))
I always appreciate your help!!!
Hi Fabio please find attached a working example of the correlation plot. I do not know much about the corrplot package so probably the plot does not make sense.
Hope it helps
Hi Fabio I managed to make the proper plot by making a small modification in thr R code.
Please find attached the example.
Tks but I can't download this file.
Can you check?
Hi Fabio, sorry for the bad upload, please see with this file
Now I understand ! You used the R View node and wrote in a different way!
Thanks for the explanation but I don't now why is not working here...It's requiring corrplot package but I already have installed.
Error in R code: "Error: there is no package called 'corrplot'"
Hi Fabio, I set up R in File/Preferences/R and I installed the corrplot package in R.
Please see the image:
Hope this helps
